A map is drawn to a scale of 1 cm to 250 cm.

Darina [25.2K]

Answer:

0.0015 km².

Step-by-step explanation:

It is given that a map is drawn to a scale of 1 cm to 250 cm.

$1\ cm\times 1\ cm=250\ cm\times 250\ cm$

$1\ cm^2=62500\ cm^2$

It is given that an airport has an area of 240 cm² on the map. So, its actual area is

$Area=240\times 62500\ cm^2$

$Area=15000000\ cm^2$

$Area=\dfrac{15000000}{10000000000}\ km^2$

$Area=0.0015\ cm^2$ $[\because 1\ km^2=10000000000\ cm^2]$

Therefore, the area of airport is 0.0015 km².

An apartment complex on Ferenginar with 250 units currently has 223 occupants. The current rent for a unit is 892 slips of Gold-

Triss [41]

Answer:

Step-by-step explanation:

Given data

Total units = 250

Current occupants = 223

Rent per unit = 892 slips of Gold-Pressed latinum

Current rent = 892 x 223 =198,916 slips of Gold-Pressed latinum

After increase in the rent, then the rent function becomes

Let us conside 'y' is increased in amount of rent

Then occupants left will be [223 - y]

Rent = [892 + 2y][223 - y] = R[y]

To maximize rent =

$\frac{dR}{dy}=0\\=2(223-y)-(892+2y)=0\\=446-2y-892-2y=0\\=-446-4y=0\\y=\frac{-446}{4}=-111.5$

Since 'y' comes in negative, the owner must decrease his rent to maximixe profit.

Since there are only 250 units available;

$y=-250+223=-27\\\\maximum \,profit =[892+2(-27)][223+27]\\=838 * 250\\=838\,for\,250\,units$

Optimal rent - 838 slips of Gold-Pressed latinum

One pipe can fill a tank in 6 hours while another can empty it in 2 hours. how long will it take to empty the full tank if both

pogonyaev

The drain pipe can drain (1/2) of the tank in 1 hour.
The fill pipe can fill (1/6) of the tank in 1 hour.
Working together, the pipes will drain the tank in (1/2) - (1/6) hours.

(1/2) - (1/6) = (3/6) -(1/6) = (2/6) or (1/3) of an hour.
So, working together, it will take 3 hours.
